+ <para>
+Compute the inverse Walsh-Hadamard transform of x using the Fast Walsh-Hadamard Transform (FWHT) algorithm. If the input is a matrix, the inverse FWHT is calculated along the columns of x.
+The number of elements of x must be a power of 2; if not, the input will be extended and filled with zeros. If a second argument is given, the input is truncated or extended to have length n.
+The third argument specifies the order in which the returned inverse Walsh-Hadamard transform coefficients should be arranged. The order may be any of the following strings:
+ </para>
+ <para>
+"sequency"
+The coefficients are returned in sequency order. This is the default if order is not given.
+ </para>
+ <para>
+"hadamard"
+The coefficients are returned in Hadamard order.
+ </para>
+ <para>
+"dyadic"
+The coefficients are returned in Gray code order.
+</para>
